Источники информации, прин тые вотвнимание при экспертизе . 1. Патент Японии № 28490, кл. 12 С 213, опублик. 1970. The invention relates to the field of pressure treatment of materials, in particular to methods for obtaining bimetallic wires. A known method of manufacturing a wire from an aluminum core and a sheath, supplied in the form of a tubular copper billet, is subjected to reduction and hermetic treatment in the temperature range 200-300 ° C. The core is fed into the cladding zone in an inert gas atmosphere 1. A disadvantage of the known method is that aluminum wire for reducing the oxide layers directly under the gas shield is pressed into the pipe by means of pressure created by an expensive press unit. There is also known a method of manufacturing bimetallic products, which involves heating aluminum billets to a temperature of 350-530 ° C, welding around them in an inert environment of copper tape, and then rolling or drawing to the required size 2. The disadvantages of this method are the limited size of the resulting products and additional energy consumption for heating the product. In addition, when processing, in particular, drawing, having surfaced on the surface of the storage billet, oxide films are destroyed along their length, thus forming heterogeneous compounds, which degrades the quality of bimetallic products. According to the proposed method, in order to increase the quality and strength of the fabricated wire, prior to forming, the aluminum wire is subjected to surface treatment in a protective medium before the oxide layer is removed, and the compression of the workpiece is reduced to a cross section of its original from 50 to 85%. In order to implement the proposed method, the surface treatment of aluminum wire obtained, for example, by casting, extruding or other known methods, is carried out in the atmosphere of the protected gas by mechanical means, by milling with brush mechanisms. At the same time, cleaning the surface from contamination, such as fatty residues, is carried out using a solvent, for example, ethylene tetrachloride. The proposed method includes the following technological operations. The surface of the aluminum core is treated in a protective gas atmosphere. Around the core prepared in such a way is applied with a continuous sweep of the median tape so that the edges lie above the core and at some distance from it. Ribbon edges are welded. Following the welding process, with | Now the closed copper tube extends to fit to the aluminum pipe. After the copper tube is completely seated on the core, both of them are drawn together, at least 50-85% with respect to the initial cross-section. Claims The method of continuous manufacture of aluminum wire clad with copper, in which a longitudinally supplied copper tape is molded into a pipe around a continuously supplied aluminum wire, is welded to the edges of the latter and the resulting workpiece is crimped in cross section, characterized in order to improve the quality and strength of the manufactured wire before forming the aluminum wire is subjected to surface treatment in a protective environment before removing the oxide layer, and the compression of the workpiece is carried out with a decrease in Niemi its cross sectional 07.50 to 85% relative to baseline.
